Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit ^9.5.0 || ^10.0 || ^11.0, found phpunit/phpunit[9.5.0, ..., 9.6.x-dev, 10.0.0, ..., 10.5.x-dev, 11.0.0, ..., 11.5.x-dev] but these were not loaded, likely because it conflicts with another require. Problem 2 - brianium/paratest is locked to version v7.6.1 and an update of this package was not requested. - brianium/paratest v7.6.1 requires phpunit/phpunit ^11.4.4 -> found phpunit/phpunit[11.4.4, 11.4.x-dev, 11.5.0, 11.5.x-dev] but it conflicts with your temporary update constraint (phpunit/phpunit:^9).
